The host of the children's television program "Mister Rogers' Neighborhood" will visit Binney & Smith's Forks Township plant at 10 a.m. Tuesday to pour wax that will make the 100 billionth crayon.

Rogers for years has included a segment on his show that describes how crayons are made. It was taped at the plant, Moran said. More than 700 episodes of "Mister Rogers' Neighborhood" have been shown on public television since 1968. He also was chosen because his "contributions to children and positive influence on families is unparallelled," Moran said.

Rogers will pour a special batch of blue crayons, which will contain the actual 100 billionth crayon. After officials determine which one that is -- and they can tell, Moran insists -- company security will take it away under lock and key.

After a production run of about 1 million blue ribbon crayons, each one destined for a limited-edition Crayola 96 Big Box, the color will never be made again.

Ten of the blue ribbon crayons will be wrapped in gold foil. Each colorer who finds a golden crayon will win a trip to the grand opening of the Crayola Factory, the company's new family discovery center in downtown Easton, and a chance to own the 100 billionth crayon.

The winner can keep it forever -- or have the company buy it back for a $100,000 bond. The crayon will be enshrined in the Crayola Hall of Fame, which will be housed in the downtown Crayola Factory.

"We're pretty confident that they'll take the $100,000," Moran said.

More than 1,100 other foil-wrapped blue ribbon crayons are good for prizes. Colorers with silver foil-wrapped crayons get a giant blue ribbon crayon replica, and red foil crayons are good for a plush toy.

The game ends June 10. Limited-edition Crayola 96 Big Boxes will be available in stores nationwide.

Binney & Smith has been manufacturing crayons since 1903, and makes more than 2 billion crayons a year.
